Laura Gough, 2009 Above ground plant and below ground stem biomass in the Arctic LTER dry heath tundra experimental plots, 2006, Toolik Lake, Alaska. 10.6073/pasta/447aec542efb8fd505b85f90c35ea47e |
Above ground plant and below ground stem biomass, percent nitrogen, and percent carbon were measured in the Arctic LTER dry heath tundra experimental plots. Treatments included control, and nitrogen and phosphorus amended plots for 10 years, and exclosure plots with and without added nitrogen and phosphorus. |
Gaius Shaver, Laura Gough, 1999 Quadrats were harvested for aboveground biomass from eight plots within a tussock, watertrack, and snowbed community at 3 sites - acidic tundra and nonacidic tundra near Arctic LTER Toolik Plots and acidic tundra near Sagwon,Arctic LTER 1997.. 10.6073/pasta/cf45e059c576273ec58ce24769793f28 |
Quadrats were harvested for aboveground biomass from eight plots within a tussock, watertrack, and snowbed community at 3 sites - acidic tundra near Toolik (site of acidic LTER plots), nonacidic tundra near Toolik Lake(site of non-acidic LTER plots), and acidic tundra near Sagwon. All vascular species were sorted, divided into new and old growth, dried, and weighed. Lichens were separated by genus in all quadrats. In half of the quadrats (n=4), mosses were separated by species. Moss and lichen data are presented by species elsewhere (see 97lgmosslichen.txt). |

Laura Gough, 2008 Growth data was collected on four graminoid species on Arctic LTER experimental plots in moist acidic tussock and dry heath tundra 2004, Toolik Field Station, Alaska.. 10.6073/pasta/8997387154a42d594073cd9bc21283cf |
Weekly growth of plant species of three growth forms were measured in the ninth year of a long-term experiment at Toolik Field Station. The experimental treatments excluded small and large mammalian herbivores and increased soil nutrients in two arctic Alaskan tundra communities: moist acidic tussock and dry heath. This data set reports the four graminoid (both tussock and rhizomatous forms) species. Please see 2004lggrbnan for Betula nana (dwarf shrub) growth data. |
